- Creates or refreshes an Omnisend contact for each RSVP signal.
- Helps keep event follow-up in the same audience system.
- Cuts down on copying attendee details after promotion.
Setup
Build it in a few focused steps.
- 1Connect Upload-Post and Omnisend to Notis once in the portal.
- 2Create an automation through the portal or ask Notis in a conversational channel.
- 3Tell Notis in one instruction to create or update an Omnisend contact when your event signup service sends an RSVP request to a Notis webhook.
- 4Choose the incoming webhook trigger and where Notis should report runs, then test one real RSVP.
Questions about this workflow
Does the webhook come from Upload-Post?
No. Upload-Post supplies no trigger event for this workflow. The event signup service or your backend sends the request to Notis.
Can I use this for multiple events?
Yes, if the incoming request carries enough context and your instruction explains how to handle event details for the contact.
